Why is "Hunnic art" trending?

Wikipedia Overview

The Huns were a nomadic people during the 4th through 6th centuries. There are two sources for their material culture and art: ancient descriptions and archaeology. The nomadic nature of Hun society means that they have left very little in the archaeological record. Although a great amount of archaeological material has been unearthed since 1945, as of 2005 there were only 200 positively identified Hunnic burials producing Hunnic material culture. It can be difficult to distinguish Hunnic archaeological finds from those of the Sarmatians, as both peoples lived in close proximity and seem to have had very similar material cultures. Kim thus cautions that it is difficult to assign any artifact to the Huns ethnically. Also, given the large numbers of culturally Germanic graves from the heart of Attila's empire, it is possible that the Huns in Europe adopted the material culture of their Germanic subjects. Roman descriptions of the Huns, meanwhile, are often highly biased, stressing their supposed primitiveness.
